Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The use of fighting clothing under extreme heat conditions during rest and exercise, compromises the body's ability to maintain temperature within the narrow physiological range needed for regular function, and might lead to heat injury. Beside working and fighting clothing, the fighters also wear vests used for protection and equipment carrying, which leads to substantial reduction in effective dissipation area from the central region of the body. This fact is most substantial during exercise which increases metabolic heat production rate and leads to heat accumulation and rise in body temperature. Therefore the development of new textile technologies to allow rapid cooling during intervals is of great importance.

This study is designed to physiologically examine new textile solutions, by evaluating the physiological stress induced during exercise under mild heat conditions.
